A spring 27 co-operating with a peg 23 secured to the. lide 26 tends tomaintain said latter in its position shown a FIGS. 7 and 8, in which theopening of the bore 21 closed by the pusher 25. The mounting of arelease able has the eliect of repelling the pusher 25 into the iteriorof the knob 22 without moving the lever 24.

It is to be observed that the placing of the cable in osition, in thetwo cameras described, does not necesitate any particular operation andthat the bore adapted receive the connection of cable is re-closedautomatical- 'y' when removing said latter.

In modifications, it is also possible to provide securing members forthe cable, other than screw threads. in articular, it is possible to usea bayonet joint. It is use to be mentioned that the cable has noparticularity vnd that for this reason it ispossible, withoutinconvenence, to use cables of normal construction for actuatin hesecameras'from a distance.

I claim: p

1. In a photographic apparatus intended for use with I. remote controlcable having an unthreaded actuating rortion and a threaded connectorportion, a casing having in internally threaded opening for receivingthe threaded :onnector portion of the cable, a film release mechanism, llever medially pivoted in the casing and having an arm for cooperationwith the release mechanism and also havng a tail portion, a springengaging said tail portion to Jias the arm away from the film releasemechanism and cave a gap for idle movement, and pusher means freely:lidable axially under the influence of said tail portion in :aidinternally threaded opening and normally maintaining ts outer end in aposition to flushly close said internally hreaded opening until thethreaded connector portion of he cable forces the pusher means inwardlyto close the gap. 1

2. In a photographic apparatus according to claim 1,,

vherein the pusher means includes a cylindrical portion :lidable in saidinternally threaded opening of the casing and said cylindrical portionis connectedwithia, blade engaging the tail of the lever opposite thearm which engages the release mechanism.

3. In a photographic apparatus for use with a remote :ontrol cablehaving an unthreaded actuating portion and a. connectorportion havingsecuring means; i t

a release member, actuating means for said release member, a casing,

an opening in said casing having securing means and adapted to receivethe mating unthreaded actuating portion of said remote cable and to alsoreceive the securing means of the connector portion,

pusher means in said casing for engaging said actuating means,

said pusher means including a pusher head filling said opening andfreely slidable therein,

spring means urging said pusher means to hold it in a first position sothat the outer face of the said pusher head is substantially flush withand fills the outer end of said opening when said remote cable isdisconnected from said casing,

said release member, actuating means, and pusher means comprisinginteractingelements positioned and arranged to provide a gap between twoof said elementswhen said pusher means is in said first position,whereby, i c

initial movement of said, pusher head to a second position afterinsertion of the unthreaded actuating porurged to said first position bysaid spring means, is

spaced from said actuating means to provide said gap, whereby saidrelease member may be activated either by displacing said knob and saidfirst slide to activate said actuating means or by inserting theactuating portion of the cable in said casing with subsequent movementof the actuating portion against said pusher head.
